Where's My Ball?

I was playing in a Jamboree on September 8, 2018 at High Cliff Golf Course in Sherwood, WI. Hole 4 is a par 3, uphill and over water, so I decided to use my 3 wood. I saw it hit the green and got into the cart. When my partner and I got onto the green - we couldn't find my ball - we looked all over for it. And then I looked into the cup - and to my surprise - there was my ball!! My first hole-in-one!!
